We report UV photodissociation action spectra of copper nitrate cluster anions Cu(NO3)3-. The parent ion decays upon electronic excitation by loss of neutral NO3 fragment. THe gas phase spectrum is similar to but slightly more structured than UV absorption spectra of solutions of the parent salt Cu(NO3)2. We discuss our experimental results in the framework of quantum chemical calculations.
